Reaction Steps
4-Hydroxyphthalic acid (3.50 g, 19.2 mmol) and K2CO3 (23.9 g, 173 mmol) in acetone (100 mL) and water (50 mL) were stirred at rt for 15 min. Benzyl bromide (20.6 mL, 173 mmol) was added and the mixture was heated under reflux for 3 d. Vacuum distillation (45°-50° C./1.1 mm) removed residual benzyl alcohol and the distillation residue was purified by gradient flash chromatography (10-30% ethyl acetate:hexane) to give dibenzyl 4-benzyloxyphthalate (7.20 g, 83%) as a pale yellow oil. TLC Rf 0.65 (25% ethyl acetate:hexane). ##STR413## Step 2
